Stock indices closed mixed as debt talks between Greece and its creditors ended without a deal. Next Eurogroup's meeting is scheduled to be on Saturday.

European Commission President Jean-Claude Juncker said on Thursday that officials will "work until the last minute, second, millisecond so that the euro project does not crash".

Earlier, Greek Prime Minister Alexis Tsipras said that he was confident that a compromise that will help the Eurozone and Greece to overcome the crisis will be reached. He added that he thinks the current proposal is a "good basis" for a deal.

Meanwhile, the economic data from the Eurozone was soft. German Gfk consumer confidence index fell to 10.1 in July from 10.2 in June. Analysts had expected the index to remain unchanged at 10.2.

The decrease was driven by declines in economic expectations and the willingness to buy. The previously unsuccessful attempts to find a solution to the debt crisis in Greece and a possible Greek default also weighed on the index.

The Confederation of British Industry released its retail sales balance data on Thursday. The CBI retail sales balance dropped to +29% in June from +51% in May.

The decline was driven by a drop in grocery sales as the supermarket price wars continue.

Sales expectations for next month eased.
